Magento 2 Field dependency in ui form

Question

I have created a ui component form. I want to display some fields based on status value. Display other fields only if status is 1. How Can I achieve it?

Here is my code

<field name="status">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="label" xsi:type="string" translate="true">Status</item>
                <item name="visible" xsi:type="boolean">true</item>
                <item name="dataType" xsi:type="string">number</item>
                <item name="formElement" xsi:type="string">select</item>
                <item name="source" xsi:type="string">status</item>
                <item name="dataScope" xsi:type="string">status</item>
                <item name="validation" xsi:type="array">
                    <item name="required-entry" xsi:type="boolean">true</item>
                </item>
                <item name="options" xsi:type="array">                       
                        <item name="0" xsi:type="array">
                            <item name="label" xsi:type="string">Pending</item>
                            <item name="value" xsi:type="string">0</item>
                        </item>
                        <item name="1" xsi:type="array">

I have added a js component in the status field

  <field name="status">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">

});

Have an idea about hide/show select option on update?
